Slope is the change in y over the change in x. (-9, -6) and (-9, -8).
-6-(-8)/-9-(-9)==>-6+8/-9+9==>2/0==>Slope is undefined
There are cases in slope where it is zero or undefinied. The slope is zero when there is zero change in the y points. Undefined occurs when there is zero change in the x points.
